This is really not an egcs question, so I suggest to take it to one of
the C++ newsgroups. The best way of doing what you want depends on
your application; if this is really about printing "int" and
"something else", templates are for you:

template<typename T>
class foo
{
public:
	typedef T hi;

	void doit (void)
	{
		if (sizeof(hi) == sizeof(int))
			puts("int");
		else
			puts("something else");
	}
};

int
main ()
{
	foo<double> s;

	s.doit();
}
